    摘要: A method and apparatus for determining the velocity of a rotating device is described herein. The apparatus includes a magnet assembly affixed to a rotating shaft of a rotating device and a circuit assembly. The circuit assembly includes a circuit interconnection having a sense coil and sensors affixed thereto. The circuit assembly is adapted to be in proximity to the magnet assembly, wherein the magnet assembly combines with the circuit assembly to form an air core electric machine such that voltages generated from the sense coil exhibits an amplitude proportional to the velocity.

    摘要: A method of determining velocity of a shaft is provided. The method includes receiving a first shaft position signal and a second shaft position signal. Derivatives of each of the first shaft position signal and the second shaft position signal are computed, as are squares of each of the derivatives, a summation of the squares, and a square root of the summation. The velocity is output as a result of the square root.
